trade help!

[Millhouse]

I have a few options this week;

T.Mitchell - downgrade
McKenzie - Hanley

$333,500 for last two rounds

Priddis - Cotchin
McKenzie - Hibberd

$23k left - downgrade & Beams next round - put Murphy on the Bench for finals

Mitchell - Watson
McKenzie - Hanley

$13 k left - downgrade & Beams next round - put Murphy on the Bench for finals

I'm not too sure - Murphy could man-up and avg 100 for the rest of the year.
McKenzie has Port, St. Kilda & GWS left - you'd expect them to win 2/3 and he could score well
Voss sacked - what willl happen to Hanley's output?

I'm leaning towards three, what's your thoughts, FanFooty?
